You can keep them both on puppy food for as long as you like. I know a breeder who never takes her dogs off of puppy food because they need the extras for nursing and pregnancy so everyone gets puppy food since they all share food. Her puppy are extremely healthy.
Puppy food is different from adult food because of the higher fat content so what you need to watch for is that the older one doesn't get fat. But a Yorkie is consider a puppy until age one. At one year , you can switch to adult food safely so you don't have that long of an overlap.
I am feeding a one year old and a 5 month old both puppy food. I feed them both in their crates so that I can control the amount of both of them. This way should the older one get too plump, I can cut her back. I can also be sure that the younger one can get as much food as he needs without having the older one determine that for him. So far it's working out well. Sometimes they do get confused on which crate is theirs but that is mostly on the puppy's part. LOL puppies are so goofy! |
